| Preshift Mean (SD) | Postshift Mean (SD) | p Value | |
|---|---|---|---|
| Heart rate (bpm) | 77.8 (9.8) | 83.9 (8.7) | 0.14 |
| Exhaled CO (ppm) | 8.3 (6.9) | 49.4 (32.7) | 0.001 |
| Systolic blood pressure (mm Hg) | 116.7 (9.5) | 115.5 (10.18) | NS |
| Diastolic blood pressure (mm Hg) | 69.3 (5.2) | 69.6 (8.4) | NS |
| Salivary cotinine (ng/mL) | 23.8 | 27.9 | NS |
NS, not significantly different in comparing preshift to postshift.
CO, carbon monoxide.
